3 Description
The TL7700 is a bipolar integrated circuit designed
for use as a reset controller in microcomputer and
microprocessor systems. The SENSE voltage can be
set to any value greater than 0.5 V using two external
resistors.
Circuit function is very stable, with supply voltage in
the 1.8-V to 40-V range. Minimum supply current
allows use with ac line operation, portable battery
operation, and automotive applications. The TL7700
device is designed for operation from –40°C to 85°C.
